Is that what you thought your daughter was, and that a tumor would become your successor?<quoted text>
So what, face reality and STFU.
A zygote is much like a tumor.
Reality is that the creation of life is not parasitical or symbiont but is an evolutionary advantage in the survival of species by procreation.
So far from parasitical a zygote is a extension of yourselves to carry on your genes after you are gone.
Parasites are always an invasive organism of another species.
The human body creates the zygote, which is mutually supportive and can generate tissue and antibodies for the mother also.
Of course it has to have a host in the beginning, but your own flesh and blood is a sacrifice that is a natural consequence
of procreation. So only a convoluted type thinking can consider
a pregnant woman host to a parasite, a pregnant woman is host to her developing baby.
